ZJB/B Series Roots Vacuum Pump

The difference between ZJB -B type with relief valve Roots vacuum pump and ZJ -B type Roots vacuum pump is that the ZJB -B type pump inlet and exhaust are connected, and a self-weight valve is installed vertically on the channel, whose role is to keep the pressure difference between the exhaust and the intake in a controllable value, which is the highest pressure difference allowed when the pump operates reliably. Therefore, this valve is actually an overload automatic protection valve.
